I'm not following you here Doc. If the OP's complaint was of cold hard starts I could understand this better (i.e., pressure leaking away overnight). But since cold hard starts apparently aren't a problem, the notion of fuel pressure loss as the cause puzzles me. Symptoms seem more like leaky injectors flooding the engine after it's been running and then sitting awhile, but still hot. What am I missing?
